private

Not Implemented.

virtual bool DtComponentSystem::init ( )

virtual

Reimplemented in DtTopLevelComponentSystem.

virtual bool DtComponentSystem::initializeFromDescriptor ( int &  priority, bool  remoteOnly  )

virtual

Creates the components and systems specified in the descriptor for the system. The first component is created with the specified priority, and priority is incremented for each component created. The next available priority value is return in priority.

Parameters

remoteOnly

If true, then only components configured for remote objects are created.

virtual bool DtComponentSystem::postAddComponentsInit ( )

virtual

Calls DtSimComponent::postAddComponentsInit() on all contained components.

virtual void DtComponentSystem::tick ( )

virtual

Calls DtSimCompoennt::tick() on all contained components.

virtual DtString DtComponentSystem::name ( ) const

virtual

Returns

The name that is supplied as the RW name of the system in the system definition.

virtual DtString DtComponentSystem::fullName ( ) const

virtual

Returns

A string that uniquely identifies this system on the entity. This name will be composed of the parent system's full name and this system's name, as returned by name().

virtual DtString DtComponentSystem::systemName ( ) const

virtual

Returns

The name of this system from the system descriptor

virtual DtString DtComponentSystem::printName ( ) const

virtual

Returns

A string that is the human readable print name, i.e. the system name in the metadata.

virtual void DtComponentSystem::setPrintName ( const DtString &  name )

virtual

Sets the print name of the system. This function can be used by components that have customizable display names in their descriptors, e.g. the range ring names for guns. The customizable names may be important for identifying the system if more than one system of the same type is included on an entity.

virtual DtSimComponentNetwork* DtComponentSystem::componentNetwork ( )

virtual

Returns

The component network that is used by this system.

virtual const DtSimComponentNetwork* DtComponentSystem::componentNetwork ( ) const

virtual

Returns

The component network that is used by this system.

virtual DtComponentSystem* DtComponentSystem::lookupSystem ( const DtString &  printName )

virtual

Finds a system within this system that matches the given print name. If this system matches, it is returned; otherwise, the systems in the component network are checked recursively.

Returns

the first component system inside this one that matches the name

virtual DtComponentSystem* DtComponentSystem::lookupSystemFromRwName ( const DtString &  rwName )

virtual

Finds a system within this system that matches the given name. This function tests the given name against the RW name rather than the print name of the system. If this system matches, it is returned; otherwise, the systems in the component network are checked recursively.

Returns

the first component system inside this one that matches the name

virtual DtComponentSystem* DtComponentSystem::lookupSystemFromFullName ( const DtString &  fullName )

virtual

Finds a system within this system that matches the given name. This tests the given name against the full name rather than the leaf name of the system. If this system matches, it s returned; otherwise, the systems in the component network are checked recursively.

Returns

the first component system inside this one whose full name matches the given name

virtual void DtComponentSystem::getSystemNames ( std::list< std::string > &  nameList ) const

virtual

Adds the system's print name and the names of all subsystems in this system to the list in nameList.

virtual DtVrfProcessStateRepositoryManager* DtComponentSystem::processStateRepositoryManager ( )

virtual

Provides a list of all of the systems, by print name, in this system.

virtual std::list<DtString> getSubsystemList();

Returns

The process state repository manager that manages all PSRs for this system.

virtual void DtComponentSystem::resolveSystemOutput ( const DtString &  outputName, DtComponentPortList &  componentOutputs  )

virtual

Within systems, connections are made from components to "system" or vice versa. This designates that as a public input/output to the system. External connections can be made to these named connections, which in turn result in a connection down to the actual component within the system. These methods take the system connection name and resolve it to the internal components and ports on those components. Each method fills the second parameter with a list of component pointers and port names on that component that should be connected to.

virtual void DtComponentSystem::resolveSystemInput ( const DtString &  inputName, DtComponentPortList &  componentInputs  )

virtual

Within systems, connections are made from components to "system" or vice versa. This designates that as a public input/output to the system. External connections can be made to these named connections, which in turn result in a connection down to the actual component within the system. These methods take the system connection name and resolve it to the internal components and ports on those components. Each method fills the second parameter with a list of component pointers and port names on that component that should be connected to.

virtual void DtComponentSystem::enable ( )

virtual

Enables/disables components/systems in the system.

virtual void DtComponentSystem::disable ( )

virtual

Enables/disables components/systems in the system.

virtual bool DtComponentSystem::isEnabled ( ) const

virtual

Check if the system is enabled, component's tick function will be called, otherwise it will not. Default is true (enabled).

virtual void DtComponentSystem::setIsEnabled ( bool  yesNo )

virtual

Check if the system is enabled, component's tick function will be called, otherwise it will not. Default is true (enabled).

virtual bool DtComponentSystem::canBeDisabled ( ) const

virtual

Check if the system can be disabled.

virtual bool DtComponentSystem::addAttributeProviderFunction ( const DtString &  attributeName, genericAttributeProviderFunctionType  attributeFunction, void *  controller  )

virtual

Functions for defining system attribute functions, and getting attributes.Adds a function that will provide the value of the given attribute. The name-function pair is put in the map myReadableAttributes. The function should create a new DtReaderWriter of the appropriate sub-type (e.g., DtRwInt, DtRwString, etc.) and return a pointer to it. Users of this data are responsible for deleting it. Controllers should call, in their init functions, these functions to register attributes the controllers support. The call in the controller will use their mySystem object.
If there was already a function registered for the same attribute, this add... function will do nothing; i.e. this is not an error. Thus some care must be used in defining attribute names, but usually the registrations work as desired. For example, in a movement system there may be several task controllers all of which use a move-along-route controller that provides a next-waypoint-index attribute (e.g. move-along, patrol-route). If the move-along controller registers to provide the attribute, all derived controllers will fail when they register. However, if all these controllers get the attribute data from the same PSR, the correct information will be returned for patrol-route even if move-along provides the attribute value.

Returns

true if there was an error trying to add this function. false if the entry was inserted in the map successfully.

virtual bool DtComponentSystem::addAttributeSetFunction ( const DtString &  attributeName, genericAttributeSetterFunctionType  attributeFunction, void *  controller  )

virtual

Similar to above, but adds a function to myWritableAttributes. The function registered here should take a Reader-Writer value and check its type before using its value. It should return True if there is an error.

virtual DtReaderWriter* DtComponentSystem::getAttribute ( const DtString &  attributeName, bool &  error  ) const

virtual

Retrieves the attribute value (by running the function mapped to this attribute).The status of the get is returned in the error parameter.

Returns

A pointer to a new DtReaderWriter containing the value of the attribute. This will be NULL if there is some error.

In the error argument–true if there was an error (i.e., the attribute does not exist; false if the query was successful.

virtual bool DtComponentSystem::setAttribute ( const DtString &  attributeName, DtReaderWriter *  value  )

virtual

Sets the attribute value (by running the function mapped to this attribute). The value is passed in as a Reader-Writer. This function does not delete the RW.
Note that setting an attribute can be used to trigger actions.

Returns

True if there was an error (i.e., the attribute does not exist; false if the "set" was successful.

virtual std::list<std::string> DtComponentSystem::getAllAttributeNames ( ) const

virtual

Gets the names of all of the attributes that have been registered by provider (i.e., Get) functions for this system.

virtual DtComponentSystemPSR* DtComponentSystem::processStateRepository ( )

virtual

Returns the process state repository used by this system.

virtual void DtComponentSystem::updateImgui ( )

virtual

Reimplemented in DtTopLevelComponentSystem.

virtual bool DtComponentSystem::createPsr ( )

protectedvirtual

Creates the PSR and sets it to myProcessStateRepository.

void DtComponentSystem::removeCompatibilityPsrs ( )

protected

Non-virtual because it is called by the destructor.

virtual void DtComponentSystem::restore ( DtSimComponentList *  )

protectedvirtual

Iterates over all components and calls onRestore on them.
